Table 1.
Study population characteristics and clinical outcomes after out-of-hospital cardiac arrest. Categorical data are presented as counts and percentages, continuous data as medians and interquartile ranges (IQR). Kruskal–Wallis tests and chi-square tests were used to assess differences between subgroups. LP (Lifepak) CR Plus: Physio-Control, Redmond, WA, USA; HeartStart FRx: Philips, Amsterdam, The Netherlands; HeartStart HS1: Philips, Amsterdam, The Netherlands; LP 1000: Physio-Control, Redmond, WA, USA; ROSC = return of spontaneous circulation; CPC = cerebral performance category (favourable neurological outcome defined as CPC 1 or 2).
